I knew someone whose roommate was extremely noisy at night. They would play loud music or have friends over late, not caring that others were trying to sleep. The person tried to talk to the roommate about it, but the roommate was very rude and said they could do whatever they wanted in their own place. This made the living situation unbearable for the other roommate.
The lack of respect for personal space is the worst. For example, if a roommate constantly barges into your room without knocking or uses your personal items without permission.
My worst roommate horror story involves a roommate who had a pet without permission. The pet made a mess all over the place, chewed on furniture, and was not properly trained. The other roommates were allergic to the pet, but the roommate with the pet didn't care and refused to get rid of it or keep it in control.
Well, in one of those bad roommate situations, my roommate used to bring over unruly friends all the time without asking. They were noisy, smoked inside when it was not allowed, and left a horrible smell. It was a constant source of stress and made it difficult to relax at home. I had to talk to my roommate several times about it, but they didn't seem to care.
A horror story could involve a roommate who steals. I knew someone whose roommate took small things like money from their wallet or borrowed clothes without asking and never returned them. It created a lot of tension and mistrust in the room. Eventually, it led to a big fight and one of them had to move out.
Lack of cleanliness is a common one. Like dirty dishes piling up or not taking out the trash. Another is being noisy at inappropriate times. Also, stealing or using others' things without permission shows up a lot in these stories.
Well, 'Worst Roommate Ever' isn't based on a true story. It's a work of imagination crafted by the writers to keep you on the edge of your seat with its drama and suspense.
One of the worst horror stories could be 'The Shining'. The isolation, the haunted hotel, and Jack Torrance's descent into madness are truly terrifying. Another might be 'Psycho' with its infamous shower scene. And 'The Exorcist' where a young girl is possessed by a demon.
